# which filter class names to use for filtering hosts when not specified in the request. scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter

Setting image architecture property to ppc64 ensures, that the nova-scheduler filters compute nodes with ppc64 architecture, which is also the architecture for Power compute nodes.

The ImagePropertiesFilter, filters hosts based on image properties. The filter checks for architecture, hypervisor_type, among other things.

More details on nova-scheduler is available here – http://docs.openstack.org/trunk/config-reference/content/section_compute-scheduler.html

There are no other Power specific configuration required. Rest of the configurations are as per requirement, and common across architectures.
